and FRANK M. ROGERS, citizens of the United States, and residents of Bay Shore, in the count of Suffolk and State of New York, have lnvented a new and Improved then acted on dirt from the floor as the Floor Scrubbing and Mo ping Machine, of which the following is a ull, clear, and ex- .act description.

--This invention relates to floor cleaning machines of that type including a rotary scrubbing brush and a mop operative behind the brush to take up the soapy water and machine is run over the latter.

The present invention has for its general objects lto improve and simplify the construction of machines of this character so as to be reliable and eflicient in use, comparatively 'simple and inexpensive to manufacture and so :designed as to insure a better cleaning `of the iioor surface by reason of the novel arrangements of the instrumentalities which are embodied in the machine.

A morespecific object of the invention is the action* of the wringer the dirt-bearing portion is sprayed with soapy water and 4y a high speed revolving 'y brush to remove the dirt, sand and tle like esv and discharge such matter into a suitably 'arranged tank.` 'y 1 A further object of the invention is the provision of simple, eifective and novel means for compensating for the shrinking and stretchingl of the endless mop and for maintainingt e same with a portion in its most eifectlve relation to the door surface 'for mopping u thedirt and water.

A further o ject is to provide .a novel wringer which is removably mounted in the frame of the machine and composed of hingedly connected sections whereby the wrlnger the mop.

An additional 'Objectis the em loyment of a sprinkling device for sprin ling soapy vvater from the reservoir or ,tank to thel ioor ust inv advance of therotary scrubbing rush and also to the dirty portion of the mop, to insure a better cleaning thereof, the sprinkling; device being controlled vby a can be opened to receive or release suitable means operable from the handle of the machine. i

' A further object of the invention is to provlde a machine which can be easily pushed over the oor and isoperative only.

during the forward motion, the design and arrangement of the parts being such thatr 'larity in the following description and claims appended hereto. l

In the accompanying drawings, .which illustrate one embodiment of the invention and wherein similar characters of reference indicate corresponding vparts all the vlews, f

Figure 1 is a side view of the machine; Fig. 2 is a vvertical section thereof;

Fig. 3 is a plan view of the machine Fig. 4 is a side view of .the wringer, portions in section, on the line Liff-4:, Fig. 2; Fig. 5 is a horizontal section von the line 55, Fig. 1;- and Fig. 6 is a detail sectional view on the line 6 6, Fig. 1.

Referring to the drawing, A designates a frame of any approved construction which is provided with handles 1 for convenience in moving the machine from place to place or over the surface to be'washed. In the present instance the operating parts of the machine derive power from large traction wheels 2 which bear on the ioor surface, but, if desired, the power may be derived from an electric motor suitably arranged on the "frame, The wheels v2, which are at the rear ratchet wheels 5 wlth'each of which copcrates a pawl 6 on the adjacent traction wheel 2,whereby rotation of the wheels In a clockwise direction,A Fi s'. 1 and 2, 'will 'f drive the shaft or axle 3,- t at in turn transi mits power tothe-various operating devices I Vof the machine; and rotation of the trac-l tion wheels in `the opposite direction, as when the machine is moved backwardly, does not impart power to the-operating devices as the pawls 6 idly ride over the teeth of the ratchet wheels 5 At the front of the lio " 4machine are fore-wheels 7 mounted on an These bearings are vertically'adjustab axle. 8 which is journaled' in bearings 9.;

e'in guides 10 by means of set-screws -11 which by being turned can bring the scrubbing brush into The scrubbing'brush B, which is of the e .I rotary type, is mounted with its axishori-A zontal, and the journals 11 on the ends thereof are' disposed in vbearings in the bottom passes a driving belt-14, t e same extendin sidebars 12 of the frame. Fastened-to one end of the brush .is a pulle 13 around'which upwardly at. one side of the machine an running around an intermediate pulle A15. This pulley is in turn .drivenbya bet 16 which passes around a pulley 17 that'is connected'with fa .large `surocke't wheel 18. En et wheel is a chain 19' wheel`20 that is turn connectedl with the main shaftjor axle 3 by `gear wheels 2 1 At the front part of the machine is a tank C-which contains water,.as shown in Fig. 2,

The feed of the water as'well as the turning onor cutting olf thereof .from'the-tank is controllable from the -handle 1 -byvany suitable means, such as; a valve 26 in the ipe 25, which valve has an.

The mop-'is drivenbythe dirt Afrom the mop, a revolving cleaning this roll can be adjusted to different posi-7 4tions as the. mo contracts orA stretches."

' These rolls .31 an 32 are parallel and they `maintain the lower part or stretch of theendless mop in proper relation withthe',

floor surface'and' ress the-mop against the same. The mop'a so passes aroundrolls 35 'and 36 mounted, res ectively behind the scrubbmg brush B an adjacent the-top of l the machine, 'and ata ointabove the roll 36 the mop passes aroun the lowerroll-37 of the wrlnger E, thence downwardly to the coacting rolls 37 and 3810i -the T wringer,

. journal extended to carry proper relation with the iioorj l x traction wheelsf2 by means-of the wherebyl the water is tively. The wringe be opened to permit the mou -Laiaeae Y m0 up the water and The rolls 37 an 38 ofthe wringer are connected together vby gears 39, and the lowerroll 37ghas one -the sprocket wheel 18 and the .pulley 17. n this' manner the rolls.of -the wringer are driven. from the and 22, sprocket wheel 20, sprocket chain'19 and sprocket wheel 18. The rolls 35 and 36v are removabl mounted, 'as are .also the rolls gears 2l I" 31 and 32, w ereby the endless mo Ycaribe removedfrom the machine. As-is own inv y Fig. 6, they-roll 35 or 36 has one journal 40 entered in an opening 41 'in one side of the frame and the other journal A42 restsin a bearing 43 at the opposite side ofthe frame and is removably held in suchbearing 43 by a 'cap late the ro ercan be li d out of the bearing 43 and thenpulled longitudinally to disengage theournal 40 from the Ajournalbearing '41.

Byremoving the cap plate e wringerE is made with its frame in two .sections 'e-'and e', and these sections are hingedl connected at one .end fof the frame by the inge 45, lwhereby th upper section e can be swung upwardly and to one side vof its normal position so as to permit the mop to .be inserted betweenl or remj'oved from the .rolls 37 and 38. of the wringen Obviously before the wringer can be opened or taken -out 'of the machine they teeth 16 .and the sprocket chain19 are \first.removed 'from the pulley 17 and .sproket wheel .'18, respec. from the machine, a d forthis purpose the cal guideways or recesses 46, asf shown in machine, and by means of theseset-screws the wringer can be 'raised or lowered -to located within the endless mop and directly under the wringers'o as to catch'the itbeing un erst'ood that t e mop travels in an anti-clockwise direction, Figs. -1 and 2.

This sprinkler is connected'with the pipe by a branch 5l which 'has a valve 52 `for regulating the iiow of water.

The mop is wider than the gage of the machine, or in other ywords, the supportingwheels lie .within or between lines coinciding with the edges Aofthe mop. Furthermore,

the rear wheels run in contact with the mop so that the latter keep thewheels clean and -they will not leave streaks on the floor.

. with the apparatus which we now consider to be the best embodiment thereof, we `desire to have it understood that theapparatus shown i'slmer'ely illustrative and that such changes may. be made when desired as fall within the scope of the appended claims.
